 - The MoinMoin wiki engine (`services.moinmoin`) has been removed, because Python 2 is being retired from nixpkgs.

+- Services in the `hadoop` module previously set `openFirewall` to true by default.
+  This has now been changed to false. Node definitions for multi-node clusters would need
+  `openFirewall = true;` to be added to to hadoop services when upgrading from NixOS 21.11.

+- `services.hadoop.yarn.nodemanager` now uses cgroup-based CPU limit enforcement by default.
+  Additionally, the option `useCGroups` was added to nodemanagers as an easy way to switch

 - The `wafHook` hook now honors `NIX_BUILD_CORES` when `enableParallelBuilding` is not set explicitly. Packages can restore the old behaviour by setting `enableParallelBuilding=false`.

 - `pkgs.claws-mail-gtk2`, representing Claws Mail's older release version three, was removed in order to get rid of Python 2.
